A padlock having a lock body defining an interior cavity includes a locking mechanism operably disposed within the inner cavity. A shackle is releasably lockable to the body in the closed position for securing an object, and movable to an open position for receiving and releasing the object. A protective sheath is attached to the shackle so as to substantially encase exposed portions of the shackle in the closed position. The sheath defines a closed space between the sheath and the lock body for securing an object, and is movable with the shackle into an open position for receiving and releasing the object.
